The time course of osmoregulatory adjustments and expressional changes of three key ion
transporters in the gill were investigated in the striped bass during salinity acclimations. In …

In zebrafish (Danio rerio), six distinct Na+-K+-ATPase (NKA) α1-subunit genes have been
identified, and four of them, zatp1a1a. 1, zatp1a1a. 2, zatp1a1a. 4, and zatp1a1a. 5, are …

Na, K-ATPase (sodium pumps) provide the primitive driving force for ion transport in bran-
chial epithelial cells. Immunoblots of epithelial homogenates of both seawater (SW)-and …

Bull sharks, Carcharhinus leucas, are one of only a few species of elasmobranchs that live
in both marine and freshwater environments. Osmoregulation in euryhaline elasmobranchs …

Ion and acid–base regulating mechanisms have been studied at the fish gill for almost a
century. Original models proposed for Na+ and Cl− uptake, and their linkage with H+ and …

We compared seawater tolerance, gill Na+/K+-ATPase and Na+/K+/2Cl–cotransporter
(NKCC) abundance, and mitochondria-rich cell (MRC) morphology of three salmonids, lake …

Recent works have emphasized the importance of a ouabain sensitive Na+ K+ ATPase∗
in the process of teleost salt-water adaptation. The implication that Na+ K+ ATPase is …

Osmotic and ionic regulation in the Crustacea is mostly accomplished by the multifunctional
gills, together with the excretory organs. In addition to their role in gas exchange, the gills …

The secondary active Cl− secretion in seawater (SW) teleost fish gills and elasmobranch
rectal gland involves basolateral Na+, K+‐ATPase and NKCC, apical membrane CFTR …

The fish gill is a multipurpose organ that, in addition to providing for aquatic gas exchange,
plays dominant roles in osmotic and ionic regulation, acid-base regulation, and excretion of …
